TimeEvolutionSolver

class TimeEvolutionSolver(backend, map_type=None, trotter_steps=None, shots=1000)[source]

Solver class that solves time evolution problem by either analog simulation on fermionic hardware or trotterized time evolution on qubit hardware. The computation that this time evolution solver will do depends on the type of the backend.

Initialize a time evolution solver

Parameters:

  • backend – The backend on which to execute the problem, may be qubit or fermionic.

  • map_type (Optional[str]) – The fermion-to-qubit mapping required if a qubit backend is given

  • trotter_steps (Optional[int]) – The amount of trotter steps to approximate time evolution on qubit backends

  • shots (int) – number of measurements taken of the constructed circuits

Attributes

TimeEvolutionSolver.MAPPER_DICT

Methods

TimeEvolutionSolver.construct_qubit_circuits(problem)

Convert the problem to a trotterized qubit circuit using the specified map_type

TimeEvolutionSolver.solve(problem)

Solve the problem using the provided backend
